#,,,#,##,, trains  are  so  constructed  that  they ####,#,,,,
#,,###,#,, have to follow a set path. this  path is ,,,###,,,#
#,#,,###,# called  a  "railway", which is comprised ,,#,,#,,#,
###,#,,##, of two metal rails, hence its  nickname. ,##,##,###
,,###,#,#,                                          #,##,##,,,

##,#,,,,## wheels of the train and the  rail metal, ,##,###,,,
,###,,,#,# there are limits for  how  acute a curve #,##,,#,,#
#,,#,,###, can  be,  and even more so for how  much ##,#,##,##
#,##,#,,## the  ground  under  the  rails  can   be ,####,##,,
##,###,#,, sloped. thus a  railway is often not led #,,,##,#,#
,##,,###,, on top of hills, rather through them  in #,,#,####,
#,#,#,,#,# tunnels   (if   they   are   large),  or #,###,,,#,

,,#####,#, rails, but not  too close, or they  will ,,##,,#,,,
,#,,,,#### be  cut  down by  the  railway janitors. ,#,#,##,,,
##,,,#,,,, there will  be  plains,  and  bodies  of #####,#,,,

,#####,#,# trains  go  by day and  by  night. along ,,##,###,,
#,,,,####,      the way, there is information       ,#,##,,#,,
#,,,#,,,## scattered,  often  put on  top of poles, ###,#,##,#
#,,##,,#,, to be interpreted  by the train drivers. ,,####,##,
#,#,#,##,# different  parts  of  the  railway  have ,#,,,##,##
